web publishment of an exe file

[profestional]

 i have made a program (VI), i want to see its front panel in the internet explorer. I configure the web publishing
tool for that purpose. and i have successfully seen the front panel in internet explorer when i run the original VI,
but when i run the Executable (exe) file then, i am unable to see the front panel in the internet explorer, then how
i can see the front panel when the exe is running. suggest mp as soon as possible.

thanks

Hi

You have to start the web server. If you run the vi in edit-mode, the web-server is running because of the LV IDE.

Here is some documentation that tells you how to create an executable that supports remote panels. I apologise if you have already seen this Knowledgebase.

Hi,

I too have the same question... I tried to follow the link that has been given by Jack.J. But I am sorry that the link is not opening here... I would like to have more documents related to this.

Any solutions please!!!

As mentioned in the last post, you have to start the web server in the application. For this you can use a property-node of the application and set at least the active property.

Hope this helps.

Hi Thank you thomas... I followed the link below and got the solution to my problem.

however, your way of enabling the webserver programatically is fantastic. Will get back on that.

Thanks and Regards,

hi, Sreedhar T,

 I met the same problem, but I don't know how to creat the "App" property node to solve it using Thomas's method.

would you please explain more on it or attach one program to show it?

(btw, I am using LabView 7.1).

Thank you very much.

Hi XG

On the block diagram browse to the Application Control palette. There you can select a "blank" property node.

You could also use a normal property node, which you created by right clicking a control.

If you right click the node, select "Select Class" to choose the appropriate class. Just browse once to the whole structure to see what's possible. If you then choose VI Server >> Application, you can select the corresponding properties.

Hope this helps.

Hi, Thomas,

Thanks a lot for your help.

With your instruction, I have successfully created the "app" property node and set the WebSrvr.Active to true.

However, i met a new problem and cannot figure it out:

• The server can run very well in the LabView Program
• After I convert the LabView program to a exe file and run the exe file, a message window will jump out and tell me "The Web Server cannot start. Is the web Server port already in use? Try to start the Web Server on another port".
• I add  a "WebSrvr.port" property and assign one value (say 8334) to it. However, the same message window come out again when runnign the exe file and the web server cannot be started.

Would you please point out where i made a mistake?

Thank you very much.

Attached the Property Node setting

Hm - I never had a problem like this.

Do you start the exe when the LV environment is running (e.g. you're editing a vi)?

What I usually configure when using it in an exe is the WebSrvr.RootPath property.

It would be helpful if you could post your vi, so that we can have a look at it and maybe try it on our own machines.
